Research on interactive technology of Webpage block localization based on JavaScript

With the development of web applications, the main way for people to obtain information is gradually transferred to the network. XPath can be used to uniquely represent a certain position in a web page for those who are familiar with web applications. However, it is difficult to interact with a computer to locate the content of a web page for most ordinary people who benefit from the web. Thus, we propose a webpage block localization technology based on JS scripts which is convenient for human-computer interaction. The experiments prove that it shows advanced performance both in interaction mode and block mode. Also, our scheme can be integrated with crawler technology to monitor a webpage block through the interaction of webpage block localization, and it can be applied to the problem feedback module of webpage to facilitate users' feedback and suggestions.
